We existing a dual-crystal Yb:KGW laserthat iscapable to function for a Q-switched oscillator with output ability up to 24 W and pulse length of twenty ns,or to be a regenerative amplifier with output ability nearly 21 W and pulse period underneath 200 fs right after compression of chirped pulses. Each lasers have superb beam excellent with beam parameter M2

Shade-coded reflectivity of the Bragg mirror like a purpose of wavelength and angle of your incident beam.

This paper describes a femtosecond laser regenerative amplifier dependant on two Yb:KYW crystals with immediate longitudinal pumping by strong linear arrays of semiconductor injection lasers obtaining fiber output. To avoid spectral narrowing in the course of amplification and also the corresponding lengthening of your amplified pulse when it's compressed, a mix of two Yb:KYW crystals have been utilized, with the spectral maxima with the amplification shifted relative to each other and with spectral profiling with check here the amplified radiation.

Before the development of Nd:YAG, Nd3+:CaWO4 was a very important scarce-earth-doped laser acquire medium. It had been in actual fact used in the primary consistently operating crystal laser.

PDF Yb:KGW and Yb:KYW crystals have broad emission bandwidths and therefore are utilized as lasing materials to deliver ultrashort (~ one hundred-two hundred fs) large energy pulses. Immediate pump of Yb:KGW/KYW crystals with laser diodes working at 981 nm supports compact laser systems.

On the other hand, when Nd3+:YAG grew to become commercially available, the curiosity in CaWO4 dropped sharply. In afterwards several years, specific other tungstate crystals began to catch the attention of plenty of notice.

The thermal conductivity of popular double tungstates is on the order to three–four W/(K m) �?which is not lousy in comparison with other laser crystals (although various occasions a lot less than for YAG), and pretty massive compared Together with the thermal conductivity of usual glasses.
